RBI, RPM, VT Bass Rack outputs

Ok this will likely come across as a dumb question, but I can't seem to find the answer. On these pre-amps, can you use both the 1/4" and XLR outputs at the same time? For example, can you use the 1/4" into a power amp for your bass cab and the XLR out to the board as a kind of onboard DI, at the same time?

The VTRM gets the closest to the SVT power-tube overdrive.
The RPM has the most tonal flexibility over a wide range of instruments, due to its parametric mids.
The RBI has a pronounced mid-scoop, but also has a high end sparkle.
